摘要：

In a general study concerning the stabilization of high oxidation states in the La2LiVO6 Matrix using high pressure, Cr(IV) (d2) and Cr(V) (d1), have been isolated and characterized in the double perovskites La2LiV0.90Cr0.10O5.95 and La2LiV0.90Cr0.10O6. Magnetic measurements and EPR study confirm such oxidation states and suggest a local tetragonal distortion of their octahedral environment in agreement with the respective t2g2e(g)0, [Cr(IV)] and t2g1e(g)0 [Cr(V)] electronic configurations.
